A new book—"The Rabbit Who Wants to Fall Asleep"—promises to put kids to sleep by the end of its pages—and not because it’s boring. The book was created by Swedish behavioral psychologist and linguist Carl-Johan Foreseen Ehrlin and uses tricky psychological and positive reinforcement techniques to lull children into sleep. The 26-page paperback is currently available on Amazon and is the first self-published book to top its charts, beating out other best-sellers like Harper Lee’s "Go Set a Watchman."
